Remember how Facebook created a network inside a network? As Facebook grew so big as a social platform, it increasingly confined people to have a Facebook user ID in order to enjoy the access to virtually any app out there, or at least have a social experiment in it.
This network-inside-the-network state of Facebook caused it to be pretty much like an internet echochamber, and confer to it this monopoly power over our shared content and social identities.
Facebook remains far away from the reality of losing its social swag, and the reason is that people perceive it as their virtual ID that merges best with their actual physical ID (real names, real connections, etc.) , than any other network.
However, this very fact of having to share almost anything we share elsewhere back on Facebook in order to consolidate our social brand/ID is what could be possibly making Facebook in the future an aggregator of our third party apps content rather than an originally shared content.
More often nowadays, you see people share content via their instagram accounts, twitter, path, runkeeper, the panoply of self-tracking apps, and others. The reason being the need to consolidate our data in one social network, the original one and that with the highest usership, Facebook.
The outcome, although irrelevant on the outside, has its implications on the business model of Facebook, that mostly relies on ads.
Now the good news is that Facebook owns Instagram. Although teens are falling for this media-only sharing app versus the larger network, and increasingly spending more time on it, Facebook can still be considered the owner of those users. And, apparently, the one-billion dollar app will start monetizing as of next year, according to the recent news.
However, regarding its competition with other platforms, like twitter, tumblr., snapchat, Facebook should be looking into what is appealing for users and especially teens, making their experience considerably more fun and engaging, more niche, and less infested by parents and unwanted friends than it has been with the so-far Facebook experiment; to avoid becoming a place we visit just to see what people are doing on other platforms.
